The research study aims to establish how and why languages adopt a rigid, apparently unmotivated gender system over a seemingly more useful, meaningful classificatory system. How do these varying systems impact our understanding? To answer these questions, the research team have developed an innovative method for investigating how grammatical categories like gender come to exist. By combining experimentation with linguistic fieldwork, they can test theories that would otherwise be out of reach. A range of techniques including card-sorting, storyboards, eye-tracking, and category training will be conducted to access speakers’ judgements and reaction times in order to assess the mental effort required for each system.

Professor Corbett said, ‘The very existence of gender is a source of confusion. For example, why in Russian is “elbow” masculine, while “knee” is neuter and “bone” is feminine? Why do some Dutch speakers distinguish three genders, and others only two? The origin of grammatical gender is a major question in linguistics and the issue of how entities are categorised by speakers of different languages is a key question in psychology.’

To demonstrate the origin of gender fully, the team will track the rise of a completely new gender system across a group of closely related languages, and they will need sufficient speakers of each language to investigate their systems of classification psycholinguistically. A group of six languages in the South Pacific islands of Vanuatu and New Caledonia have been identified as meeting all of these requirements, exhibiting intriguing signs of this grammatical development.

This research will provide insight into the way in which humans categorise entities in the world, and how this categorisation is incorporated into the workings of language. These two aspects of research provide a rare opportunity to investigate how the mind codifies human experience. At the end of the project, the research team aim to provide an experiment toolkit which will provide a template for conducting experiments in other areas.

Dr Grandison said, ‘Our findings will provide the foundations for new hypotheses about the development of categorisation more generally. The different language communities will benefit from literacy materials detailing the use of the different classifier and gender systems found, which will aid language education efforts for this tricky area of language.’
